IS-6 Anyone?

The IS-6 is a Soviet tier VIII heavy tank. The armour on the tank is relatively thin but it is very well sloped, giving a good defensive capability. The tank is equipped with the 122 mm D-30 gun. This has a relatively low penetration, so you will need to adjust your tactics and aim for enemy weak spots, but the gun is capable of delivering a lot of damage with a good rate of fire.
